Even now, we scarcely understand the nature of that blue ray, the Cold Ray, as it is now called. We know that all things in its path acted as if under the influence of extreme, unheard-of cold, absolute zero. It was exactly as if the invaders had concentrated utter cold and hurled it forth in a single stabbing ray. Strictly speaking, of course, there is no such thing as positive cold, only absence of heat. The theory generally accepted now is that in some unexplained manner the ray had the power of instantly sucking away the heat of anything it touched.

Certain it was that the ray was a terrible weapon. Beneath it, flesh and blood froze immediately into black hard lumps, metal cracked, trees and plants shriveled instantly...

It seems that as the Cold Ray swept around the city, it crossed, ever and again. the city's harbor and the sea outside. And for many days afterward, immense icebergs of unprecedented size ranged the English coast, born of that striking of the ocean by the blue ray.
